There are 60 * 60 = 3600 seconds in an hour.
First find out how many meters will be travelled in one hour by multiplying by 3600.
Distance travelled in 1 hour = 0.088 * 3600 meters.
Next convert the distance to kilometers by dividing by 1000. So the speed in kilometers per hour is given by:
\[0.88\times \frac{3600}{1000}=(you\ can\ calculate)\ km/hour\]
